Hi,I am interested in feeding the EEPROM (and only them) with a software without uploading the complete source code and writing through the EEPROM library. I do not know where to start so any hints or tutorials are welcome.

So the last digit of 4711, 4712, is to keep track of where the message is to go?Will there be some end character so if comm's get messed up the receiving arduino can recognine that and respond accordingly, or ignore the message, or similar?
